Yes, Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects.
OOP focuses on creating objects that contain both data and methods to manipulate that data.
Key principles of OOP include encapsulation, inheritance, and polymorphism.
Examples of OOP languages include Java, C++, and Python.
A constant in PHP is a variable whose value cannot be changed during the script execution.
Constants are defined using the define() function in PHP.
Constants are case-sensitive by default.
Constants can be accessed globally.
Example: define('PI', 3.14);

Polymorphism is the ability of an object to take on many forms. Encapsulation is the practice of hiding data and methods within a class. Inheritance is the ability of a class to inherit properties and methods from a parent class.
Polymorphism allows objects to be treated as if they are of different types.
Encapsulation helps to protect data from outside interference and misuse.
Inheritance allows for code reuse and promot...
Stacks are a data structure that follows the Last-In-First-Out (LIFO) principle. They are used to store and retrieve data in a specific order.
Stacks have two main operations: push (to add an element to the top) and pop (to remove the top element)
Examples of stacks include the call stack in programming languages, undo/redo functionality in text editors, and the back button in web browsers

C++ has better memory management with features like constructors and destructors.
C++ has more advanced features like templates and exceptions.
C++ is more versatile and can be used for both low-level system programming and high-level application development.

Find all possible combinations of 2 elements in an array of length N whose sum is 10.
Iterate through the array and for each element, check if there exists another element in the array whose sum is 10.
Use a nested loop to compare each element with every other element in the array.
Store the pairs of elements whose sum is 10 in a new array.
Return the array of pairs.
Linked list is better than array for dynamic memory allocation and insertion/deletion operations.
Linked list allows for dynamic memory allocation, while arrays have a fixed size.
Insertion and deletion operations are faster in linked list as compared to arrays.
Arrays have better cache locality and are faster for random access.
Linked list is used in applications like implementing stacks, queues, and hash tables.
Arrays ar...
Binary search finds the position of a target value within a sorted array. Merge sort and bubble sort are sorting algorithms.
Binary search: repeatedly divide the search interval in half until the target value is found or not found
Merge sort: divide the unsorted list into n sublists, repeatedly merge sublists to produce new sorted sublists until there is only 1 sublist remaining
Bubble sort: repeatedly swap adjacent eleme...

To open the number lock on the bag, you need to try combinations of three numbers, ensuring that at least two of them are correct.
Start by trying the combinations of the first two numbers with each of the remaining six numbers.
If none of these combinations work, move on to the next pair of numbers and repeat the process.
Continue this pattern until you find a combination that opens the lock.
